Option strategies
Straddle, strangle, spread, butterfly, iron condor
Option strategies combine calls and puts. This guide explains the common ones in plain language — what they are for, what you can gain or lose — then opens a calculator that draws the picture at expiry.
What are option strategies?
An option is the right to buy (a call) or to sell (a put) an underlying — a share, an index, a currency — at a predetermined strike price, by or at a set date. You pay a premium for that right; you are not obliged to use it.
The strike price is simply the price written in the contract. Option strategies put several calls and puts together: to bet that the price will rise or fall, that it will move a lot, or that it will stay in a range. Names you will see below — covered call, cash-secured put, straddle, strangle, spread, butterfly, iron condor — are just those combinations.
At expiry, each option is worth what it would pay if you used it that day (or nothing). Before expiry, the vanilla option calculator estimates a theoretical price. The strategy pages draw that result as a chart.
A few useful words
- Call
- The right to buy the underlying at the strike price.
- Put
- The right to sell the underlying at the strike price.
- Strike price
- The agreed price in the option contract.
- Premium
- What you pay to buy an option, or receive if you sell one.
- Underlying
- The asset the option is written on — the thing you have the right to buy or sell.
- Assignment
- When an option you sold is exercised against you: you must buy or sell the underlying at the strike price.
- Out of the money (OTM)
- A call with a strike price above the market, or a put with a strike price below. It would pay nothing if expiry were today.
Which strategy matches what you expect?
Use this as a map, not a recommendation. Then open a calculator and change the strike prices and premiums until the chart matches the idea you have in mind.
| If you think… | Look at | Why |
|---|---|---|
| The price will rise | Long call, bull call spread | You want to benefit from a rise. The spread is cheaper and also caps how much you can make. |
| The price will fall | Long put, bear put spread | You want to benefit from a fall. On a long put, the most you can lose is the premium. |
| A large move, either way | Straddle, strangle | You do not pick a direction; you need a move larger than what you paid in premiums. |
| The price stays in a range | Butterfly, iron condor | You expect a quiet market. The loss is limited; the gain is largest if the price stays in the middle. |
| You sold an option and want to see the seller's side | Short call / put | The most you can keep is the premium; losses can be large if you do not add a hedge. |
| You already own the shares and want extra income | Covered call | You collect a premium. If the shares are called away, you miss further upside above the strike price — a missed gain, not an unlimited loss. |
| You would be happy to buy the shares at a chosen price | Cash-secured put | You set cash aside, collect a premium, and buy at the strike price if assigned. |
Long call and long put
The simplest strategies: buy a call if you expect a rise, buy a put if you expect a fall. You pay the premium up front. That premium is also the most you can lose.
- Risk — Limited to the premium paid.
- Reward — Call: can keep rising if the price rises. Put: grows if the price falls toward zero.
- When to use — You have a clear up or down idea and you want a known maximum loss. Strike prices farther from the market are cheaper but need a bigger move.
Short call and short put
Selling a call or a put (without buying another option as a hedge) collects a premium. The trade works if the option expires unused or you buy it back cheaper. The risk is the opposite of buying: a sold call can lose without a cap if the price keeps rising.
If you already own the shares, a covered call is a different picture: the shares cover the sold call, so the main cost is missed upside rather than an uncapped loss. If you set cash aside to buy the shares, see the cash-secured put.
- Risk — Sold call: no cap. Sold put: large if the price falls toward zero, minus the premium you received.
- Reward — Limited to the premium received.
- When to use — You expect a quiet market or a modest move away from the strike price, and you accept a large loss if you are wrong. Many people cap that risk with a spread instead.
Covered call
A covered call means you already hold the underlying — for example the shares — and you sell a call against those shares. The buyer of that call has the right to buy them from you at the strike price. You keep the premium they pay you.
People use it to collect that premium as extra income. If at expiry the stock is still below the strike price, the call expires unused (it is worth nothing) and you keep both the shares and the premium. In that case there is no capital loss from the option itself.
- Risk — The main cost is missed upside (opportunity cost). If the stock rises above the strike price and the call is exercised, your shares may be called away: you sell them at the strike. You do not pocket the further rise. That missed gain is not the same as the unlimited loss of a short call sold without the shares, because you already own the stock that covers the call. If the stock falls, you still own it and can lose on the shares; the premium only cushions that a little.
- Reward — The premium, plus any rise in the shares up to the strike price.
- When to use — You already own the shares, you would be willing to sell them at the strike price, and you want extra income if the market stays quiet or rises only a little.
Cash-secured put
A cash-secured put (CSP) means you sell a put while cash is reserved — set aside — to buy the shares if you are assigned. Assigned means the put buyer uses their right to sell: you must buy the underlying at the strike price.
The benefit: you collect a premium. If the put expires out of the money (OTM) — the stock stays above the strike price — the put is unused and you keep both the premium and your cash.
If you are assigned (the stock is below the strike price), you buy the underlying at that strike. That can be useful if you wanted to own it anyway, at that price, with the premium as a small discount.
- Risk — After assignment you own the stock. If it keeps falling, you can lose on a mark-to-market basis, like any shareholder. The cash sitting idle could also have been used elsewhere (opportunity cost). The premium cushions a fall only a little.
- Reward — Limited to the premium if the put expires unused. If assigned, you own the shares at the strike price minus that premium.
- When to use — You would be happy to buy the shares at the strike price, and you accept that the cash must stay reserved until expiry.

Call spread and put spread
A vertical spread buys one option and sells another of the same type at a different strike price. The sold option helps pay for the bought one, so you spend (or receive) less than with a single option, and both the gain and the loss are capped by the gap between the two strike prices.
- Risk — Known in advance: what you pay if you buy the spread, or the gap between strike prices minus what you receive if you sell it.
- Reward — Also known in advance: the gap minus what you paid, or the premium you received.
- When to use — You think the price will rise or fall but do not need unlimited gain, or you want to sell premium without leaving the loss uncapped.
Straddle
A straddle is a call and a put with the same strike price, usually near today's price. If you buy both, you pay two premiums and you need a large move either way. If you sell both, you keep those premiums and you want the price to stay still. You roughly break even if the market moves by the total premium.
- Risk — Buying: the two premiums. Selling: a large move either way can lose without a cap.
- Reward — Buying: grows with a big move. Selling: you keep the premiums if the market finishes near the strike price.
- When to use — Around an event, when you expect a large move but do not want to pick up or down. Compare what the options cost with the move you actually expect.
Strangle
A strangle is the two-strike-price cousin of the straddle: a cheaper call above the market and a cheaper put below. It costs less than a straddle at today's price, so you pay less, but the market must travel farther before you get that money back. Selling a strangle still loses a lot if the price breaks out.
- Risk — Buying: both premiums. Selling: large or uncapped if the price leaves the range.
- Reward — Buying: a move beyond the farther strike price, after the premiums. Selling: you keep the premiums if both options expire unused.
- When to use — You want a cheaper way than a straddle to bet on a large move, or a wider quiet zone if you sell. An iron condor adds extra options that cap that sold strangle.
Butterfly
A long butterfly buys one option at a low strike price, sells two at a middle strike price, and buys one at a high strike price (all calls or all puts). The best result is if the market finishes at the middle. The outer options cap the loss at what you paid. It is a limited-risk way to bet that the price stays near one strike price.
- Risk — Limited to what you pay (when you buy the butterfly).
- Reward — Limited too: largest if the market expires at the middle strike price.
- When to use — You expect the price to finish near one strike price and you want a known maximum loss. Selling a butterfly is the opposite: you want a large move away from the middle.
Iron condor
An iron condor is a put spread plus a call spread: four options, with a limited loss on both sides. You typically receive a net premium and keep it if the market expires between the two inner strike prices. Losses start if the price crosses an inner strike price, and they stop at the outer one.
- Risk — Known in advance: the wider of the two spreads, minus the premium you received.
- Reward — Limited to that premium if both sold options expire unused.
- When to use — You expect the price to stay in a range and you prefer a known maximum loss to selling a strangle with no cap. Wider inner strike prices pay less and need a bigger move before you lose.
